Bitcoin is indeed risky. But bank investments are risky too. In our country (coz I'm not sure if this exist in other countries). When you have a large amount on your account they will call you and ask you if you want to invest, minimum of 20,000 Php (or 400 USD). They will propose some investment plans where there is a choice of low, medium, or high risk investment. When you choose the high risk there is a chance to lose or gain 100% of your investment (Medium is 75% and low is 50% if I remember it right). It doesn't make sense to me, it sounds like a scam, they will invest using your money and you don't have any control to it. That is why I like bitcoin more, coz Though it is risky and it's very volatile, you have full control on your investment.
What do you guys think?
With the question what is riskier, I would say it depends on each individual level of knowledge and understanding of investments! If you have little knowledge on how the bank would use your money to generate income and if they will not explain it thoroughly to you, that is more riskier for me. When cryptocurrency was introduced, I never thought that you can have full control of your investment wherein you can cut your loss anytime when market goes wrong. Yes, its true that the market is volatile but if you know how to play along, you can create massive wealth with it. I am part conservative with my investment because I do invest also in a bank and also put my hard-earned money in holding potential altcoins.
